First,
we
always
advise
everybody
to
treat
each
other
with
respect
to
no
harassment,
no
discrimination
and
so
on.
We
are
an
open
community
and
that's
important
for
us
to
have
a
good,
a
good
relationship
together
and
also
we
do
have
some
anti-trust
policy.
I
I,
if
you
you
want
you
to
to
know
a
little
bit
more.
Please
go
through
the
week
at
the
for
high
political
foundation,
student
to
know
a
little
bit
more
about
the
undertrust
policy
of
hyperledger
and
some
other
some
other
information
we
are
going
to
after
the
presentation.
B
A
B
C
So
I
just
wanted
to
highlight
that
what
I
will
try
to
cover
today
and
we'll
go
for
it.
Sorry
for
the
quickly
since
I
have
a
fair
amount
of
material
here
is
a
little
bit
of
an
overview
of
blockchain
technician
to
sort
of
a
set,
the
stage
for
what
we
are
seeing
and
where
I
believe
we're
going
to
see
in
a
significant
uptake
talk
than
a
cow.
We
implemented
it.
C
As
you
know,
hyperledger
fabric
does
not
have
a
built-in
token
mechanism,
and
so
we
can
work
to
implement
one
in
the
oracle
version
as
an
application
chain
code
essentially
capability.
But
it's
a
little
bit
more
interesting
because
we've
also
created
a
local
development,
tooling
platform,
so
that
people
that
want
to
use
tokens
don't
have
to
necessarily
write
a
lot
of
code
or
you
know,
be
chenco
development
experts
and
I'll
show
you
that
as
well,
then
we'll
talk
about
customer
examples
and
some
use
cases
leveraging
tokenization
and
I'll.
C
A
C
The
presentation
no
problem,
all
right,
all
right,
so
let's
get
started
right
and
I'll
start
with.
You
know
some
basics
here,
for
those
of
you
who
may
not
be
in
the
thick
of
things
may
not
be
familiar
with
what
the
organization
really
mean.
Everybody
heard
the
term
right,
but
I
kind
of
like
to
go
back
to
the
basics
right.
What
do
we
mean
by
tokenizing
an
asset?
Well,
what
we
mean
is
representing
it
in
a
blockchain
ledger
often
so
it
doesn't
have
to
be
a
blockchain
ledger
in
the
ways
it's
self-describing
right.
C
C
What
else
can
you
do
with
tokens
and
why
is
it
useful
and
of
interest
to
enterprises?
I
mean
oracle,
as
you
know,
typically
focused
on
enterprise
kind
of
customers
right
and
so
what
we
see
in
our
conversations
is
that
many
customers
are
looking
to
use
tokens
to
track
digital
assets
or
physical
assets
through
a
digital
twin
concept.
C
C
C
So
you
know
historically,
of
course,
when
you
know
tokenization
started
in
the
you
know,
blockchain
and
cryptocurrency
environments,
and
that's
what
we
know
and
still
here
to
this
day
is
the
most
about,
of
course,
with
ethereum.
You
get
programmable
tokens
based
on
smart
contracts
and
now,
of
course,
you
have
new
emerging
networks
like
flow.
For
example,
you
know
polygon
and
so
on,
supporting
nft
marketplaces.
C
C
But
you
know
all
of
us
who
really
like
hyperledger
fabric,
you
know
really
stuck
because
we
don't
have
native
token
support
now.
That
does
not
mean
that
you
cannot
run
application
chain
code
to
emulate
erc20,
rc721
and
many
customers.
Many
of
our
customers
and
partners
have
done
that
and
you
essentially
have
common.
You
know,
building
blogs
that
people
use.
C
You
know,
there's
a
question
here
about
tokenizing
a
funeral
plot
to
facilitate
as
a
resale.
It's
an
asset
right,
so,
of
course
it
can
be
tokenized
and
you
can
do
more
traceability.
You
could
all
you
know
if
you
wanted
to
do
fractional
ownership
and
things
like
that,
so
I'll
talk
whipping
as
a
question
about
difference
between
fabric
oracle,
blockchain
and
ibm
blockchain.
C
C
So,
let's
see
now,
of
course,
most
recently
we've
been
seeing
a
lot
more
about
non-fungible
tokens.
I
pulled
this
from
101
blockchains.
Just
you
know,
looking
at
the
different
types
of
scenarios
where
nfts
can
play
and
from
our
own
conversations
right,
we
talk
to
retailers
who
are
essentially
interested
in
this
omni-channel
experience
right
how
they
engage
their
customers.
The
consumers
and
nfcs
play
strong
roles
there.
C
When
we
talk
to
logistics,
customers
they're
really
excited
about
nfts
as
a
way
to
represent
electronic
bills
of
lading,
which
are
negotiable
documents,
meaning
they
get
the
ownership
changes
as
a
shipment
goes
through.
You
know
the
line
from
freight
forwarders
to
shippers
in
ascending
port
receiving
port
customs.
All
of
that
so
representing
bill
of
lading
in
an
nft
format,
provides
some
really
cool
capabilities
companies
in
a
products
business
who
needs
to
trace
them
pharmaceuticals
certified.
C
We've
talked
to
manufacturing
companies
who
are
using
nfts
to
represent
the
inventories
and
then
take
that
to
a
digital
market
for
inventory
financing
right
in
some
industries.
In
some
areas,
inventories
represent
a
significant
capital
and
they
want
to
have
it
financed
rather
than
you
know,
spend
their
own
working
capital
on
it.
C
In
investment
space
in
capital
markets,
we
talked
to
companies
who
are
interested
in
valuing,
what's
called
ehg
investments,
which
is
you
know,
the
type
of
investments
that
are
socially
conscious,
that
you
have
good
governance
policies.
You
know
ethical
sourcing,
all
of
those
kind
of
things
reducing
you
know,
environmental
impact,
co2
emissions
and
all
of
that
used
to
be
called
green
bonds,
but
it's
very
difficult
to
track
value
and
track
achievements
and
milestones
that
the
promises
built
into
those
investments
and-
and
if
this
can
help
with
that
as
well.
C
So
you
can
see
that
you
could
do
a
lot
more
than
just.
You
know,
having
really
cute
pictures
that
you,
trade
and
and
spend
you
know
thousands
of
dollars
on
there's
real
business
use
cases
here
now,
as
other
questions
that
we
get
asked
often
is
you
know
you
are
using
a
permission
blockchain,
which
is
hyperledger
fabric
right.
C
So
how
does
that
play
for
nfts?
Well,
let's
start
looking
at
what's
going
on
in
the
industry
today
and
a
lot
of
concerns
that
people
have
about.
You
know
open
marketplaces
and
public
blockchains
like
ethereum
right.
This
is
a
great
slide.
I
think,
processing
one
ethereum
transaction
is
equivalent
to
driving
a
car
for
500
miles
or
using
one
month
of
electricity
for
a
new
resident,
all
right,
processing
over
100
thousand
visit
transactions.
C
There's
a
lot
of
concerns
about
that
right
and
then
there
was
also
challenges
around.
You
know
security
issues
and
you
know
copycat
there's
a
lot
of
user
complaints
about
security
problems
and
fake
nfts.
You
know
performance
issues
like
nft,
gamers,
clocking
polygon.
I
mean
all
kinds
of
things
right.
Then
you
have
additional
issues
such
as
you
know:
compliance
security,
compliance
ability
to
use
fiat
payments
without
requiring
crypto
wallets.
C
C
It's
also
an
issue
right
with
open
marketplaces,
availability
and
slas,
as
well
as
integration
with
variety
of
internal
systems.
If
you
need
to
be
able
to
track
your
and
user
tracks,
the
financial
aspects
so
permission
blockchain
can
really
provide
a
lot
of
benefits.
They
could
also
interoperate
with
in
a
public
blockchains.
In
fact,
they
could
trade
enough
this
back
and
forth,
or
exchange
them
or
move
them,
but
having
permission
blockchain
as
a
core
foundation
area.
I
think
that
would
be
a
very
important
starting
point
to
solve
those
challenges.
C
So
what's
oracle's
approach
right
our
platform,
as
I
said,
hyperledger
fabric
based,
you
can
implement
erc20
rc721
and
many
have
done
this
application
chain
code,
but
we
wanted
to
create
it
as
a
more
standardized
capability
out
of
the
box
building
block,
and
so
we
use
this
development
tool.
That's
called
blockchain,
not
builder,
which
is
a
local
development
platform
to
generate
also
necessary
chain
code
from
a
specification.
C
Now,
what
specification
do
we
start
with?
Well,
we
decided
to
start
with
stock
and
taxonomy
framework
here
from
iwa,
because
it
provides
a
great
way
to
actually
define
a
meta
model
for
tokens
with
things
like
base
type,
functionable,
non-fungible,
different
properties,
the
whole
fractional
custom
properties
behaviors
all
of
those
things,
and
you
can
then
sort
of
start
with
a
definition,
create
classes,
instances
and
so
on,
using
this
hierarchy,
and
so
we
went
ahead
and
used
this
in
our
blocks.
C
In
our
builder
as
a
model
we're
here
at
declarative,
spec,
you
can
set
parameters,
you
can
set
some
values
in
that
spec
and
then
we
will
automatically
generate
the
code,
the
chain
code
methods
necessary
to
support
the
entire
life
cycle,
and
we've
released
that
last
summer.
We
actually
announced
that
the
hyperledger
global
forum
last
june,
almost
a
year
ago,
fungible
token
support
and
I'll
show
you
some
examples
of
people
using
it.
We're
now
working
on
non-fungible
tokens
based
on
the
rc721
model,
and
that
will
be
in
fact
coming
out
very
shortly
in
about
a
month.
C
So,
if
you're
not
familiar
with
ctf,
it
defines
sort
of
this.
You
know
formula
expression
for
how
to
map
token
properties
right.
Starting
with
the
base
type
behaviors
groups
of
behaviors
property
sets
and
so
on-
and
you
know
you
can
see
here-
different
proper
different
behaviors
that
can
be
associated
with
a
token,
and
all
of
that
allows
you
to
fundamentally
create
a
spec
and
then
use
that
spec
as
a
starting
point.
C
So
how
we've
implemented
it
is
starting
with
our
blockchain
platform.
So
this
is
a
quick
overview
of
oracle.
Blockchain
looks
at
based
on
fabric
pre-assembled,
there's
a
lot
of
under
in
underlying
components:
container
management,
identity,
event,
services,
option
data:
sync,
you
don't
have
to
think
about
it.
It's
all
built
in
you
can
go
into
our
cloud
very
quickly
provision
it
all.
It
has
a
lot
of
interoperability
capabilities,
so
they've
started.
C
C
C
We've
done
a
lot
of
engineering
work,
so
it's
not
just
taking
fabric
and
making
it
available
right.
It's
making
it
resilient
and
redundant
with
replication
of
high
availability.
All
of
the
dependency
integrations
quick
provisioning,
zero,
downtime,
patching
identity,
security
and
editability
enhancements
api
gateway
management
and
development.
Tooling,
database
integration
as
well
many
many
things.
C
So
you
know
we
said
kind
of
this
was
all
good
for
helping
people
to
get
to
a
production-ready
state
very
quickly
which
were
kind
of
known
for,
but
beyond
that
we
said
how
do
we
help
people
with
applications
to
start
using
blockchain?
Effectively
platform
needs
solutions,
so
we
went
to
our
industry
partners
and
have
a
lot
of
them
build
pre-built,
vertical
solutions
across
many
different
industries.
And
then
we
created
this
local
development.
Tooling.
C
The
blockchain
knob
builder,
that
can
automatically
generate
the
chain
code
for
you
from
low
code
spec
and,
of
course
it
could
manage
life
cycle
deployment,
testing
and
all
of
that,
it's
built
using
I'll
get
into
that
in
a
minute.
But
then
we
said
you
know
we
can
extend
it
to
support
organizations
as
well
as
a
low
code
capability
with
fungible
and
unfunchable
tokens.
C
C
It
has
built-in
fabric
configuration
in
it,
so
you
can
test
locally
and
then
you
can
go
ahead
and
deploy
into
our
cloud
instance
obp
running
in
the
cloud
or
on-premises
and,
like
I
said
one
of
the
key
differences
I
mean
you
know
the
kind
of
basic
deployment
life
cycle
that's
been
done
before
right,
I
mean
that's
not
revolutionary.
What's
really
distinguishing
is
the
ability
to
automate
smart
code,
continco
generation
from
specifications
right,
we're
generating
typescript
and
go
and
all
of
the
crowd
methods
all
of
them.
C
C
C
C
Well,
we
said
why
don't
we
create
a
sample
token
specification
again
based
on
dtf
and
we
allow
you
to
specify
the
relevant.
You
know
token
type
behavior
parameters
associated
with
those
behaviors
and
then
custom
properties.
You
can
extend
the
token
within
custom
method
as
well,
and
all
of
that
is
essentially
done
in
a
very
simple
spec.
We
provide
one
for
you
to
start
with.
You
can
customize
and
tweak
it
right
and
then
we'll
go
ahead
and
we'll
generate
the
actual
chain
code.
Well,
what
do
we
generate?
C
We
generate
an
sdk
which
is
a
set
of
basic
foundational
capabilities
necessary
to
support
the
ttf
behaviors
and
we
provide
the
actual
methods.
I'll
show
you
in
a
minute,
and
on
top
of
that
we
generate
a
set
of
wrapper
functions
that
manage
the
entire
life
cycle
and
make
it
easy,
including
such
things
as
role-based
security,
which
is
pretty
important
in
enterprise
applications.
C
C
Here
we
go
all
right,
so
we
generate
basic
functions
and
methods
necessary
to
manage
the
different
behaviors
right,
and
this
is
essentially
provided.
You
know
as
an
sdk,
and
then
we
surround
it
with
life
cycle
methods
right
full
lifecycle
management,
so
we
initialize
the
tokens
we
manage,
accounts
create
account
and
all
of
the
queries
we
manage
roles
and
then
the
actual
you
know
regular
operations
like
minting,
transfer,
escrow
born
and
so
on
with
because
a
great
question
was
we
integrate
with
token
builder
released
by
ngg.
C
So
it
helps
those
methods
available.
Now
we
are
with
our
api
gateway.
Everything
you
deploy.
All
methods
are
automatically
exposed
as
rest
apis,
so
you
could
start
using
this
by
simply
making
restful
calls
or
you
could
develop
more
complex
chain
code
methods
using
this
underlying
building
blocks
right
and
calls
them
from
your
chain
code
either
way.
C
So
this
supports,
you
know
the
basic
life
cycle,
but
what
we've
also
done
is
integrated
a
sample
into
our
console.
We
have
the
developer
tools
section
and
under
samples
we
included
this
fiat
money,
token
sample,
so
that
if
you
don't
want
to
go
through
the
app
builder
and
the
generation,
you
could
get
it
right
here.
You
could
play
with
it.
You
could
deploy
it
and
you
know,
then
it
has
actions
that
you
could
play
with
right.
You
can
interact
with
issuing
tokens
transferring
burning
all
of
those
things.
C
So
you
know
that's
basically
built
in
you
know
to
the
product
out
of
the
box
as
a
sample
to
start
with,
the
other
things
that
we
have
started
doing
is
looking
at,
of
course,
with
nft
support,
and
I
mentioned
we
have
everything.
We've
done
everything
I've
shown.
You
works
today
for
fungible
tokens
and
next
month
we're
releasing
non-fungible
token
as
well.
C
As
a
blockchain
platform,
you
would
need
to
build
a
marketplace
ui
some
kind
of
a
front-end
for
general
operations
right,
so
you
need
a
ux
platform
with
your
visual
builder.
For
that
purpose,
you
could
optionally
integrate
it
with
an
e-commerce
set
of
tools
for
payment
gateway
and
all
of
that,
and
then
you
have
an
nfc
marketplace.
Basically,
there
is
obviously
a
way
of
running
just
key
components
here
as
a
blockchain
platform,
content
management,
ux
platform,
and
then
you
can
add
additional
more
complete
kind
of
capabilities,
including
analytics.
C
You
know,
mobile
services,
integration
platform.
So
we
have
a
starting
architecture,
reference
architecture
for
this
weapon's
asking.
Can
we
integrate
content
management
with
storage
or
ipfs?
Yes,
we
can,
if
you
you
know,
don't
want
to
use
our
content
management.
You
can
certainly
use
ipfs
and
you
know
if
you
wanted
to
sort
party
content
repositories,
we
can
integrate
as
long
as
they
have
ability
to
make
rest
api
calls
as
you.
You
know,
upload
content
and
you
know
assemble
pieces
and
so
on.
C
C
C
The
other
scenarios
are
digital
currency,
of
course,
so
we're
pretty
active
in
cbdc
space
talking
with
a
number
of
central
banks,
as
well
as
bank
back
commercial
bank
back
digital
currency,
but
also
twins
representing
other
assets.
So
in
a
product
space
manufacturing
space,
we've
used
tokens
to
actually
enable
a
certified
supply
chain,
tracking
and
royalty
accrual
solution
in
insurance
back
office.
They
have
a
lot
of
different
silos
that
interact
with
brokers
with
agents
with
range
tourist
companies.
C
And
then
we
have
non-fungible
tokens
where
we've
seen
interest
in
areas
such
as
data
marketplaces.
There
are
companies
that
have
active
sort
of
solutions,
around
data
marketplaces,
ap
rights
and
other
things:
esg
auditability,
investing
consumer
marketplaces
for
collectibles
and
videos
and
such
and
other
things
so
I'll
show
you
a
few
of
those
examples.
C
They
had
the
loyalty
system
that
would
take
30
days
to
actually
give
you
your
loyalty
point,
so
you
would
buy
something
in
a
store
and
a
month
later,
you
get
a
statement
saying
you
have
some
loyalty
points.
Of
course
you
forgot
what
you
bought
by
zan
and
what
you're
going
to
do
with
it.
They
wanted
to
change
that
to
provide
the
real-time
capability.
So
if
you
have
a
mobile
app
with
a
wallet
and
when
you
buy
something
in
a
store
by
the
times
that
you
actually
complete
the
transaction,
you
walk
out
of
the
store.
C
C
So
that
was
really
great,
and
one
of
the
big
factors
as
well
is
multi-currency
support,
because
it's
just
in
europe
not
is
in
europe
right,
so
they
wanted
to
be
able
to
do
this,
and
you
know
essentially
use
loyalty
points
for
people
buying
in
one
country
and
then
going
to
a
game
in
a
different
country.
I
mean
just
you,
know
football
fans
and
such
he
has
a
different
project.
C
This
was
about
agriculture,
sustainable
agriculture,
a
project
that
was
supported
by
world
bank
funding
implemented
by
infosys,
which
was
a
big
system
integration
partner
of
ours.
It
was
about
provenance,
it
was
actually
implemented
in
indonesia,
for
sustainable
traceability
of
palm
oil,
palm
tree
farming
etc,
and
the
oil
mills
funded.
C
This
is
a
different
example
where
a
company
that
is
in
textile
space,
they're
responsible
for
fabrics
that
have
some
volcanic
sand
content
in
the
fibers
that
allows
them
to
keep
constant
body
temperature,
so
they're
using
athletic
sports.
That
kind
of
thing
right,
but
they
don't
manufacture
anything.
They
have
a
partner
ecosystem
that
starts
with
manufacturing.
C
This
volcanic
sand,
master
batches
shipping
them
to
fiber
companies
who
then
ship
fiber
to
yarn
companies
who
make
yarns
we
shipped
to
fabric
mills
to
make
fabric,
and
so
you
have
you
know
then
fabric
shipped
to
the
retailers
who
make
you
know,
garments
or
clothing
units,
and
so
tracking.
All
of
this
is
products
and
ingredient
tokens
on
the
blockchain
right.
You
ship
the
products
you
have
inventory
of
tokens,
you
consume
them
when
you
produce
the
next
product
in
a
chain
and
so
on.
C
Now
they
get
this
in
real
time
as
people
actually
record,
the
royalty
calculations
done
automatically
on
blockchain
and
then
they
can
issue
payments
as
well,
and
we
drive
the
digital
twin
of
the
payment
on
chain
as
well.
Here
we
can
drill
down
using
our
analytics
integration
into
any
particular
product
and
see
all
of
the
ingredients,
so
a
jacket
here
made
out
of
different
fabrics,
which
particular
fabric.
C
What
fibers
you
know
what
this
master
batch,
etc
relationships
of
the
companies
in
the
sankey
diagram,
and
all
of
that
this
was
that
insurance
case
I
mentioned
earlier,
where
there
is
different
systems
where
the
payments
are
flowing
between
brokers,
between
agents,
between
insurance,
company
reinsurer
and
by
using
the
ledger
they
can
integrate.
All
of
that
in
one
place.
C
This
is
a
more
recent
example
that
was
implemented
by
a
partner
in
italy
in
italy.
They
have
this
tradition
of
creating
christmas
trees
using
lights.
This
is
the
biggest
christmas
tree
in
the
world
apparently
implemented
built
on
the
stress,
amanda
lake.
It's
I
think
it's
a
couple,
kilometers
long
made
out
of
lights
and
they
have
an
event
and
they
sold
tickets
to
that
event
because
coveted
in
compliance,
and
they
wanted
to
maintain
the
maximum
number
of
people
at
any
time.
C
There
is
a
lot
of
issues,
it's
a
very
fragmented
industry
in
a
freight
and
shipments
and
so
on,
and
you
have
situations
where
you
know
there
is
a
lot
of
payment
disputes,
a
lot
of
administration
costs.
You
know
issues
like
temperature
deviations.
A
lot
of
trucking
companies,
90
have
six
tracks
of
euro.
So
there
is
a
lot
of
consolidation,
kind
of
matching
demand
and
supplies.
C
C
C
D
For
oracle
blockchain
platform
that
enables
the
developers
to
rapidly
test
and
deploy
the
chain
code
for
blockchain
applications
that
can
be
deployed
on
oracle
blockchain
platform.
Or
are
you
can
locally
test
using
hyperledger?
App
builder,
supports
multiple
languages,
type
script
and
go
programming,
and
there.
C
D
Rate
token
coin
tokens,
so
here
are
the
assets,
if
you're
the
for
the
bank
coin
demo
describing
the
metadata
of
the
amo
file.
Looking
at
all
the
bank
coin
token
asset,
if
you're
looking
at
the
anatomy,
this
type
is
called
fungible
open.
In
this
case
there
are
types
of
behaviors
that
can
be
defined
for,
for
this
token,
based
on
the
token
taxonomy
like
transfer,
so
we.
D
D
Such
methods
can
be
written
at
the
bottom
that
can
be
written
as
custom
methods,
in
this
case
that
initialize
bank
coin
merchants
and
transfer
bank
coin.
The
blockchain
app
builder
provides
you
with
the
simple
mechanism
to
go
and
create
the
chain
code
by
using
the
spec
file.
You
can
you
can
do
this
by
clicking
on
the
chain
codes
tab
on
the
left
hand,
side
corner
on
the
top
by
adding
the
button
over
there
and
defining
the
name
of
the
defending,
and
this
is
the
language
that
we
want
to
generate.
B
B
D
One
is
first,
one
is
the
bank
design
and
also
there
is
merchant
data
structure,
so
these
two
are
the
token.
These
two
are
the
objects
or
data
structures.
We
are
going
to
use
the
business
logic
like
create,
update,
issue,
burn
and
transfer
are
defined
in
this
controller
file
that
has
been
generated
here
are
the
custom
methods
that
are
generated
with
the
signature
to
perform
specific
custom
actions
that
are
needed
by
the
solution
of
the
application.
C
D
Ahead
and
start
deploying
with
the
url
provided
in
your
url
provided
for
rest
proxy.
This
is
the
remote
url
that
you're
looking
at
and
username
has
been
defined
as
bank
for
deploying
the
chain
code
and
testing
it.
So
we
are
saying
this
file
to
make
sure
that
we
get
the
right
connection.
You
can
see
that
the
environment
file
is
saved
so
that
we
are
ready
to
div
right.
So
just.
C
D
And
run
the
system,
api
calls
and
perform
transactions
on
our
on
our
oracle.
Blockchain
platform
here
is
the
url
that
we
are
going
to
use
for
performing
the
api
transactions
so-
and
here
is
the
body
of
the
transaction
where
we're
going
to
initialize
coin
token,
let's
go
and
perform
and
initialize
token
transaction.
C
So
we're
going
to
set
up
accounts,
so
you
see
create
account
here,
add
role
right.
So,
for
example,
the
bank
account
here's
a
mentor
all
then
we
create
account
for
retail
user.
Then
we
create
a
merchant
which
is
planning
hotel.
That's
create
account
plus
a
few
other
functions
in
the
custom
chain
code.
C
D
C
So
we
can
do
born
and
all
that,
so
anything
in
you
know
and
that's
what
sort
of
it
looks
like
on
the
ledger
right,
but
in
the
interest
of
time
I
know
we
want
to
leave
some
room
for
questions
here
as
well.
So
let
me
just
wrap
up
here.
One
thing
I
wanted
to
mention
people
ask
some
time:
how
can
you
exchange
the
tokens
with
other
platforms
and
other
ledgers?
C
There
is
a
protocol
hash
time,
locked,
atomic
swap
or
hashtag
contract
hdlc
that
basically
allows
different
ledgers
to
exchange
tokens.
We've
actually
damaged
it.
Before
I
believe
last
september
we
had
a
hyperledger
event
with
damages
with
ethereum
erc20
contract
and
now
fiat
money
token.
So
that's
a
pretty
straightforward
process
right
most
of
you,
you
know
probably
familiar,
you
can
look
it
up.
C
Just
google
htlc
we've
also
have
integration
work
done
with
quant,
which
provides
this
overledger
middleware
that
can
interoperate
with
multiple
ledgers,
and
we
have
seen
also
that
the
hyperledger
cactus
team
released.
I
believe
it
was
just
a
week
or
so
ago,
1.0
version
of
hyperledger
cactus,
which
is
an
integration
middleware
that
supports
connectors
to
multiple
ledgers
and
so
on.
C
So
we're
going
to
be
taking
a
series,
look
at
that
and
see
how
we
can
integrate
them
into
the
platform
and
leverage
it
for
cross-leg
integrations
an
example
of
nft
based
deployments,
running
currently
or
being
tested
some
partner.
Basically
with
our
partners
who
are
here,
you
know
I've
talked
earlier
about
many
many
different
use
cases
across
nft
space
that
we're
beginning
to
see
people
adopting,
and
so
just
in
closing
I'll.
C
You
know
mention
that
saturn
recognization
projects
can
be
done
on
hyperledger
fabric
people,
sometimes
shy
away
because
we
don't
have
native
token
support,
but
that
should
no
longer
be
a
barrier.
Our
capabilities
and
there
is
open
source
samples
as
well
out
there
for
how
to
do.
Tokens
on
hyperledger
fabric
are
out
there.
C
So
but
I
think,
without
builder,
with
low
code
capabilities,
we
can
significantly
help
accelerate
that
by
providing
the
slow
code
approach
with
the
ttf
model
out
of
the
box
code
generation
and
the
local
test
environment
and
automated
deployment
all
help
to
improve
developer
productivity,
a
lot,
and
so
you
know,
if
you
wanted
to
try
oracle
blockchain
and
see
how
easy
we
can
make
it.
I
would
you
know
just
I'll
skip
that.
I
would
just
suggest
that
you
go
ahead
and
give
it
a
try.
C
I
love
this
quote
from
don
topscott
about
future
being
something
that
it's
to
be
achieved
rather
than
to
be
predicted
right.
So
all
of
other
things
have
the
tools
and
capabilities
to
do
that.
You
can
get
a
free
trial
on
oracle
cloud
right
there
in
sapolo
or
13
other
cloud
locations
around
the
world,
oracle.com
cloudslash
free.
It's
that
easy
and
you
can
set
up.
I
believe
it's
30
days,
300
free
credit
and
you
can
go
ahead
and
that's
it
start
playing
with
it,
and
you
could
use
the
samples
that
I
mentioned.
C
C
A
A
A
C
C
You
know
to
our
customers
in
a
comparison
between
oracle
and
ibm
will
live
for
another
times.
There
are
some.
Both
companies
done
a
lot
of
excellent
work
in
making
blockchain
easier
to
use
faster,
more
reliable,
resilient
and
so
on,
and
you
know
and
interoperable
right.
So
you
know
if
you
wanted
to
mix
the
nodes
from
oracle,
ibm
or
open
source
fabric,
you
could
do
that
in
a
single
network.
C
C
Okay,
the
vs
code
extension
is
not
yet
on
the
vsu
marketplace.
We
do
plan
to
get
it
there.
There
are
some
protests
involved.
I
guess
you
know.
Oracle
has
to
go
through
certain
steps
and
we
are
going
to
get
that
in
place,
but
it's
not
there.
Yet,
as
far
as
create
an
issue,
I
think
we're
talking
about
create
when
you
create
you
actually
initialize
the
token
ecosystem
right
and
that's
a
step
necessary
to
set
up
the
actual.
C
Okay,
so
yeah,
so
we
could
certainly
yeah
record
that,
and
you
know,
if
you're
interested
in
learning
more,
please
reach
out
through
renato,
and
he
can
you
know,
answer
many
of
your
questions.
You
can
connect
it
with
our
team
as
well.
If
you
want
to
try
it
out,
just
you
know:
go
to
oracle
dot,
com,
slash
cloud
free
trials
and
sign
up
in
support
region
or
any
other.
B
First
of
all,
congratulations
such
an
incredible
presentation
and
such
an
incredible
tool
as
well.
It's
it's
very
impressive
to
see
how
the
all
the
things
that
you
can
be
can
it
can
do
building
chain
code
from
from
scratch.
But
I'd
like
to
ask
another
question
about
the
market.
What
do
you
think
about
the?
Can
you
access
the
risks
of
speculation
at
the
token
markets,
because
you
do
have
lots
of
things
around
nfts
and
our
erc
20
tokens
and
so
on?
C
You
know,
I,
I
think
that
you
know
we
periodically.
You
know
sees
that
type
of
a
question
when
we're
talking
to
our
you
know:
enterprise
customers,
right
business
customers,
and
I
think
the
answer
is
that
in
the
public
blockchain,
which
is
really
has
no
governance,
not
really
you
know
no
regulation,
etc.
C
There
certainly
could
be
speculation,
excesses
and
other
kinds
of
risks,
and
that's
why
we
recommend
a
permissioned
blockchain
for
most
of
the
customer
use
cases
where
they
have.
If
you
will
a
community
of
participants,
that's
authorized
and
they
can
define
and
implement
their
own
governance
policies
to
avoid
those
kind
of
things
right.
C
You
cannot
really
avoid
it
in
a
public
blockchain
environment,
but
in
a
permissioned
enterprise
blockchain.
The
governance
of
that
is
much
more
within
the
control
of
the
organizations
that
are
operating
it
operating
the
nodes
and
I
think
they
have
all
the
capabilities
necessary
to
control.
You
know
any
kind
of
risks
associated
with
using
the
underlying
blockchain
technology.
